120 Grams of Sugar to Cups
120 grams of granulated sugar equals ⅝ cup (0.6 US cups), based on 200 g per cup (level cup). In the kitchen, measure 10 tbsp. For best results, weigh granulated sugar with a scale — cup measurements vary with how the cup is filled.
This is a typical single-recipe amount, where how you fill the cup matters most: a level, consistent fill keeps batches repeatable.

How to measure 120 g of granulated sugar without a scale
